'lihis invention relates to welting or gimp used in connection with thejoining of leather and similar materials.

In the manufacture of shoes, pocket books s and similar articles ofleather or artificial leathers it is ordinary practice to form a seambetween two strips of the material by inserting what is generally knownas a seam-closing strip, which consists of a. strip of material usuallyof leather, having a solid edge which is interposed between the twopieces of the material to be joined, the other edge thereof being madeto coincide with the edges of the material. A row of stitching is thenrun l5 through the three superimposed layers. It often happens iiipractice and particularly where cheap grades of leathers or leatherettesare being joined, that as the materials are folded and creased toflatten the seam,

2o they crack during the flattening process or after short usage,thereby destroying the article with a consequent loss of bot-li laborand materials. i

With the foregoing in mind, it is the purpose of the present inventionto provide a strip of welting of this character which may be used tojoin two pieces of material wit-hout requiring a fold to be made in thelatter.

i -I accomplish this purpose by means of a Welt- 3o ing strip of thecharacter hereinafter described, set foi-thin the appended claim andillustratively exemplified in the accompanying drawings in which: Figurelis a plan view of a strip of my improved welting; Figure 2 is atransverse sectional view taken on the lines 2-2 of Figure 1 Figure 3 isa plan view of two pieces of material joined by means of my improvedwelting strip; and Figure d is a transverseI sectional view taken onlines t@ ll-l of F igure 3.

Figure 5 is a transverse sectional view of a slightly modiedconstruction;- and Figure 6 is a similar sectional view of a stillfurther modification.

Referring to the drawings, and particularly to Figures 1 and 2, 10denotes a strip of tape, preferably leather or suitably treated fabric,and 11 designates a strip of filler, usually cotton cord, which isplaced upon the tape longitudinally thereof and closer to one edge thanto the other. '.llie shorter side of 'the tape is then folded over onitself to a line short of the cord 11 and fixed by means of somesuitable adhesive. 'lhe other side of the tape 10 is also folded uponitself to overlie j the .5a cord 11 and to meet or project very slightlyover the edge of the shorter side, as shown in Figure 2. Adhesive isused to fix this side also. The weltin strip in its complete form isready to be used in seaming a great variety G0 of materials and is madeup in long strips.

Referring now to Figures 3 and ll, I have shown one application of my imroved welting in which the latter is placed etween two y pieces ofmaterial 12, the edges thereof being' 65 arranged adjacent oppositesides of the bulge .made by thc cord filling 11 and a row of stitches 13run through each piece of material 12 and the underlying side of thewelting.

It will be" clear that if the article is to be folded at the seam theWelting will be the portion taking the fold instead of material of "thearticle itself, the. solid edge of the weltin forming a beaded effectwhich may be furt er accented by utilizing a welt of con- 'i5 trastingcolor. i

In Figure 5, I have shown the welting made up of two separate strips 10of material disposed about the interposed filling or cord 11, the stripsbeing vbrought together and held by se an adhesive. In Figure 6, thewelting is made from a single piece 10 of material which is folded onitself and the side edges brought together, the filling 11 beinginterposed between the folds and the material held together by c5 anadhesive, as previously described.

Having now described my' invention what I claim as new and desire tosecure by lietters Patent is:

A welting strip, comprising a flat strip of So material folded on itselfwith side edges overlapping, a filler strip disposed centrally andlongitudinally between the layers of thel folds of the strip, the sidesof the folded material beyond the filler strip being flat to receive theD5 edges of materials to beijoined.

In testimony whereof he has affixed his signature.f Y BORIS SILVERSTEIN.I ICI()l
